Interstate highways and local roads are generally unlit outside of urban areas. But in fairness, Waymos don't operate in those places anyway.

Not always. Definitely not all freeways.

> And every car has its own lights for seeing where you are driving

Not always far enough. Especially at freeway speeds on unlit freeways.

So how can humans do it?

If humans don't have lidar but can drive it's an existence proof of the viability of that approach.

reply
In addition to vision, humans have proprioception and kinesthesia, hearing, inner ear receptors for balance, a sense of touch, sense of smell. We use all of these sensory inputs when we drive. And even then humans get into lots of accidents.

Lidar is superhuman vision.

How do you use your sense of smell to help you drive? I can't smell anything outside my car thanks to the air filter.

The real answer is very simple: safe drivers slow down to adapt to poor conditions (including visibility). Lidar might reduce how much it needs to slow down but I don't think it will be eliminated because you can't drive with only lidar.

I smell smoke before I see it. Useful if there's a forest fire up ahead.

Burning rubber or smoke from the engine is an indicator of a mechanical issue.

Nobody said you could. This is a strawman.

Tesla stans are the only ones trying to convince everyone you can only drive with cameras. Everyone else is pretty united on the usefulness of multiple inputs.

Didn't mean it in that way. I meant a car with camera+lidar would realistically still slow down because of the reduced camera visibility.

Ignore them. The latest Model S and X have radar again, but possibly unused right now, so they are probably going to roll that out in a refresh of the 3 and Y eventually.

Humans can't do it safely during a proper blizzard. (Toronto doesn't really get proper blizzards, though).
